More repeaters than your CHIRP file. Probably.

The Radioddity DB20-G is a 20-watt GMRS mobile radio that offers a good balance between power and affordability. Its compact design and straightforward feature set make it a solid option for operators who want a vehicle-mounted radio without the higher price of 50W models.
The DB20-G appeals to operators who want more power than a handheld but do not necessarily need the full 50 watts of the top-tier mobiles. At 20 watts, it provides a noticeable range improvement over 5W handhelds while drawing less current and generating less heat. The compact size makes it easy to tuck into small vehicles, UTVs, or golf carts. Its price point sits well below the 50W competition, making it an accessible first mobile radio.
20W vs 50W: In real-world use, the difference between 20W and 50W is less dramatic than the numbers suggest. Doubling power only adds about 3 dB — roughly half an S-unit on most radios. A good antenna and clear line of sight will do more for your range than extra watts. The DB20-G is plenty of radio for most GMRS use cases.
The Radioddity DB20-G is not supported by CHIRP. To program the radio from a computer, use Radioddity's own CPS (Customer Programming Software), available as a free download from the Radioddity website. You will need a Radioddity programming cable.
The CPS software lets you configure channels, power levels, tones, repeater settings, and other radio parameters. The interface is functional and covers everything you need for GMRS channel setup.
The radio can also be configured through its front-panel menu if you prefer not to use a computer.
